.To 60 whom, it may concern:

Be it known that I, CHARLES O. WYMAN, a citizen of the United. States,and a resident of Anoka, in the county of Anoka and State of Minnesota,have invented a new and Improved Finger-Bar, of which the following is afull, clear, and exact description.

This invention relates to a finger-bar for grain-harvesters.

The prime object of the invention is to provide a finger-bar which maybe adjusted around its longitudinal axis so as to change the inclinationof the finger-bar and sickle with respect to the ground, thus leavingthe stubble long or short without changing the elevation of theharvester-platform.

The present application is a division of my former application forharvesters, filed July 1, 1903, Serial No. 163,872.

This specification is an exact description of one example of theinvention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a front elevation of the cutting apparatus of thegrain-harvester, this view illustrating the form of self-bindingharvester disclosed in my copending application above referred to. Fig.2 is a side elevation of the devices for adjusting the finger-bar asabove explained. Fig. 3 is a plan view of the fingerbar with partsbroken away, and Fig. 41 is a section on the line 4 4 of Fig. 1.

indicates the harvester-platform, over which the platform-aprons run inthe usual manner, and 11 indicates the elevator-frame of the harvesterdisclosed in my copending application above referred. to. 12 indicatesthe binder-deck of said harvester, and 14 indicates the main framingthereof, all of which parts while adj unctive to are not absolutelyessential to the present invention. At each side of the front edge ofthe platform-frame 10 bearings 15 are located, andin said bearings aremounted trunnions 16, formed on the ends of the finger-bar 17. Saidfinger-bar carries the fingers 18 and the sickle 19 in the usual manner.It will be observed. that by this arrangement the finger-bar may beadjusted, as indicated by the full and. broken lines in Fig. 4, and thusthe height of the cut may be regulated without the necessity ofelevating the entire platform-frame.

20 indicates the pitman, which is provided with a suitable connection 21with the sicklebar 19, so as to drive the same, this connection beingsuch as will enable the sickle-bar to be adjusted in the mannerdescribed without in any way interfering with the driving of thesickle-bar through the pitman.

22 indicates a rock-shaft suitably mounted in boxes 23 and having auniversal con.- nection 24 with the inner. trunnion 16 of thesickle-bar. Said rock-shaft 22 has a crank 25 at its end, and tothiscrank is connected a link 26, which passes upward to an elbow-lever27, mounted on the framing 14, said lever having a spring-pawl 28coacting with the toothed quadrant 29, mounted on the frame of themachine. By manipulating this lever 27 the shaft 22 may be rocked in onedirection. or the other, and in this mannor the sickle-bar may be tiltedas described. Owing to the universal joint 34, the platform andfinger-bar may be raised. to vertical position without interfering withany of the connections between the said parts and. the parts on theharvester-frame.

Various changes in the form, proportions, and minor details of myinvention may be resorted to at will without departing from the spiritand scope thereof. Hence I consider myself entitled to all suchvariations as may lie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination with a harvester-platform, of asickle-bar mounted thereon to rock around an axis extendinglongitudinally of the finger-bar, a rock-shaft, a universal connectionbetween the rock-shaft and fmger-bar, and means for operating therockshaft.

2. In a harvester, the combination of a fin er-bar, means for mountingthe same to roc around an axis extending longitudinally of thefinger-bar and to swing bodily into vertical position, a sickle-bar,means for imparting reciprocal movement to the sickle-bar, a rockingmember for imparting said rocking movement to the finger-bar, and auniversal connection between the said member and the finger-bar.

3. In a harvester, the combination of a finger-bar, means for mountingthe same to rock around an axis extending longitudinally thereof and formounting the finger-bar to IIO swing bodily into vertical position, asickle- In testimony whereof I have signed my bar, a pitman connected tothe sickle-bar, name to this specification in the presence of 10 meansfor operating the pitman, a rocking two subscribing witnesses.
